Genuinely, where the hell did this come from?

I realized everytime I think about my own issues and what I'm struggling with I immediately shut them down with "oh I'm just being overdramatic" or/and "I'm just trying to create problems for myself, I'm so privileged"... WHY DID THIS BECOME MY AUTOMATIC REACTION??? Like. What??? Ig it's cause whenever I talked about my problems it was framed as "oh you're too young you're just feeling a lot" and "you're being hormonal" and overtime I just had to accept it... but this reaction really sucks. 🥹 I've started to gatekeep my own feelings because of this mindset even though I want to be heard by my FRIENDS. (No I won't open up to them again. It's not because they did something to me, it just feels like a huge fucking burden whenever I end up ranting and crashing out and then no one fucking replies)
